A lever has a total length of 12 meters with a fulcrum at the exact center of the lever. Which best describes how to double the mechanical

advantage of the lever?

O Move the fulcrum 2 meters away from the side on which the force is applied.

Move the fulcrum 2 meters toward the side on which the force is applied.

O Move the fulcrum 4 meters away from the side on which the force is applied.

O Move the fulcrum 4 meters toward the side on which the force is applied.

The correct option is the last option.

Explanation:

Generally, when trying to create a mechanical advantage of a lever for an apparatus or a machine, the load is usually moved closer to the fulcrum. Hence, if a lever has a total length of 12 meters and the fulcrum is placed at 6 meters (the center), the best way (based on the previous statement) to double the mechanical advantage of the lever is to move the fulcrum 4 meters toward the side on which the force is applied. The correct option is the last option.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
